TO ALL WHOM IT MAY CONCERN;

Be it known that I, E. G. CLEVELAND, of Worcester, in the county ofWorcester, and State of Massachusetts, have invented a new and usefulImprovement in Hydro-Extractors; and do hereby declare that the following is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing bad to the accompanying drawings forming part of thisspecification.

' The present invention Consists in so supporting or hanging andarranging the basket of the hydroextracfor, that is to be revolved at agreat speed, asto move about from side to side freely for a. limiteddistance, thereby changing theupright shaft from a vertical line.

In combination with the above, the invention also consists in the use ofseveral counter-weights upon the shaft to the basket, that are encased,whereby the weight of the loose substance or material in the basket tobe extracted is counter-balanced or equalized as the basket is revolved.In the accompanying plute of drawings myimprovements in thehydro-extractors are illustrated I Figure 1 being a central verticalsection through a hydro-extractor made according thereto, and

Figure 2 a transverse horizontal detail section in plane of the line xx, fig. 1.

Similar letters of reference indicate corresponding parts. v

.A, in the drawings, represents the basket to the hydro-extractor. Theside B of this basket A is formed of a series of parallel wires, a,supported at suitable points by upright bars 6, that at their lower endsare fixcd to the edge or periphery c of the circular bottom plate 0. lThe basket is fixed to and about acentre upright shaft, D, that,projecting through the bottom plate 0, is at such end placed in a step,E, that by its flanged end F is supported around the edge of an openingor hole, G, in the bottom H of the vessel or case I surrounding thebasket. The basketshaft turns on the step E, and such step canfreely:play from side to side upon the bottom to vessel I." To the uppe'r endof the basket-shaft D a pulley, L, is fixed. This pulley is made hollow,and upon its upper side is open. .M, a case surrounding pulley L, whichcase is fixed in a hori zontal position by means of curved upright armsN secured to the upper edge or rim of the vessel I. To this case M aretwo vertical openings or slots, through which passes the endless belt 0,from and around the pulley L, to and around the loose flanged pulleys RR, hung to spindles upon opposite sides of the upright S, and fromthence down to and around the pulley T, fixed upon the driving-shaftU.By this arrangement of pulleys above described the basket is driven orrevolved. The upper end to the case N, about the pulley L, is closed bya head plate, V, .fixed thereto, which plate, by its centre-piece W,projects into the hollow pulley L. This centre-piece is bored out,leaving a shoulder, a, near its lower end, on which rests the lower openend 02, to a socket, X, that by its flange Y is fixed to the upper sideof head plate V. Z, a box, made of a hemispherical shape uponitsoutside, and placed with-in the, socket X, hereinabove referred to. Fromthis box the upper end of-basket-shaft extends, and by mcans'of it thebasket, as it is revolved, can freely move from side to side, within acertain limit, as is obvious without any further explanation, theadvantages of which are self-manifest to all conversant withhydro-extractors.

Surrounding the shaft to the basket, upon the inside of the latter, isconstructed a case or boxing, A that is tightly closed. Within this boxcounter-weights B are hung to the shaft 56 as to freely turn thereon, bymetfis of which weights the weight of the material or substance in thebasket is counterbalanced as the basket is revolved.

By means of the construction and arrangement of parts above describedthe basket is allowed free action from side to side, and being balanced,will run in a vertical position or nearly so. That furthermore, howevertight the driving-beltmay be upon the pulley to the basket shaft, thebasket is free for action.

I claim as new, and'desire to secure by Letters Patentv- Thehydro-extractors, the basket, when hung for operation, substantially asand for the purposed described.

I also claim, in combination with the above, the counter-weights appliedto the basket-shaft substantially as and for the purpose specified. i
